    <p>At add_action documentation it says that</p> <pre><code>add_action( $hook, $function_to_add, $priority, $accepted_args ); </code></pre> <blockquote> <p>$hook : The name of the action to which $function_to_add is hooked. (See Plugin API/Action Reference for a list of action hooks). Can also be the name of an action inside a theme or plugin file, or the special tag "all", in which case the function will be called for all hooks)</p> </blockquote> <p><a href="http://codex.wordpress.org/Function_Reference/add_action" rel="nofollow">http://codex.wordpress.org/Function_Reference/add_action</a></p> <p>So or you either declare a action hook that is provided from wordpress core (See the list here : <a href="http://codex.wordpress.org/Plugin_API/Action_Reference" rel="nofollow">http://codex.wordpress.org/Plugin_API/Action_Reference</a>) or you can provide your action but this action, in your case the_excerpt_slider();, has to be declare somewhere in your function.php file. So that's whay you get this error. the_excerpt(); is working fine because is a core function of wordpress.</p> <p><strong>UPDATE</strong></p> <pre><code>add_action('the_excerpt','limit_the_content'); function limit_the_content($content){ global $post; if('slider' == get_post_type($post-&gt;ID)){ $settings = get_option('mytheme_options'); $word_limit_slider = $settings['numberofwordsexcerptslider']; $words_slider = explode(' ', $content_slider); return implode(' ', array_slice($words_slider, 0, $word_limit_slider)); }else{ $settings = get_option('mytheme_options'); $word_limit = $settings['numberofwordsexcerpt']; $words = explode(' ', $content); return implode(' ', array_slice($words, 0, $word_limit)); } } </code></pre> <p>In this line of code : </p> <pre><code>'slider' == get_post_type($post-&gt;ID) </code></pre> <p>the 'slider' is the name of your custom post. You have to change it to your defined name. You can find it if you go to the admin panel and go where all your sliders are shown up. In the url you should see something like :</p> <pre><code>http://yoururl/wp-admin/edit.php?post_type=slider </code></pre> <p>so the name of your custom post is after the <code>?post_type=</code></p> <p>Also inside your file you should change the <code>&lt;?php the_excerpt_slider(); ?&gt;</code> to <code>&lt;?php the_excerpt(); ?&gt;</code> </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
